Claims (8)

1. A cellular structure comprising: (a) a plurality of elongated plastic strips that are adjacent to each other, interconnected in limited areas spaced apart from each other, and can be elongated in width to form a single lattice of cells, ( b) while these strips form the walls of the cells, each of which has holes that form a certain configuration, which includes at least the first and second groups of holes, (I) each of these holes has a diameter of from about 3 mm to 17 mm, (II) each first group of holes includes a plurality of holes, the neighboring of which are spaced apart by a first distance from each other; (III) every second group of holes includes a plurality of holes, the neighboring of which are spaced a second distance from each other; (IV) each first group of holes is laterally separated from the corresponding second group of holes by a third distance greater than the first distance and the second distance, thereby creating a part free from the holes, which forms one of the limited sections located at a distance from each other , to connect the zone of one of the many elongated plastic strips with the zone of the other of the many elongated plastic strips.  2. The cellular structure according to claim 1, in which (a) said configuration further includes a third and fourth group of holes, wherein (I) each third group of holes includes a plurality of holes, neighboring of which are spaced a fourth distance from each other; (Ii) every fourth group of holes includes a plurality of holes, the neighboring of which are spaced a fifth distance from each other; (III) every third group of holes is laterally separated from the corresponding fourth group of holes by a third distance greater than the fourth and fifth distance.  3. The cellular structure according to claim 2, in which (a) every third group of holes is spaced a sixth distance in the vertical direction from the corresponding first group of holes and (b) every fourth group of holes is spaced a sixth distance in the vertical direction from the corresponding second group of holes .  4. The honeycomb structure of claim 3, wherein (a) a first distance, a second distance, a fourth distance, and a fifth distance, measured between the centers of adjacent holes, are each 0.75 inches (19.05 mm).  5. The honeycomb structure of claim 4, wherein (a) a third distance, measured from the edges of adjacent holes, is 1.6250 inches (41.275 mm).  6. The cellular structure according to claim 5, in which (a) the sixth distance measured from the edges of adjacent holes is 0.6250 inches (15.875 mm).  7. The cellular structure according to any one of claims 1 to 6, in which (a) the total area of the holes in one cell wall for the specified configuration is approximately 19% to 28% of the total cell wall area.  8. The cellular structure according to any one of claims 1 to 7, further comprising (a) at least one reinforcing element passing through a series of matching holes in the cell walls and having a nominal tensile strength of from about 100 to 2500 pounds (from 45.3 up to 1132.5 kg).
